In the present. exemplification of this invention, the machine consists,essentially, of a frame or body [5 which is supported by suitable legsi6, and may be of any desired size and configuration.

The body I5 is provided with two spaced parallel channels or grooves IT,in each of which a slide I8 is reciprocable. This slide is of aconfiguration to conform to the contour of the grooves I1, and each ispreferably provided with laterally projecting side portions l9 thatrestupon guide-ways 20, wearing. strips 2i being preferably provided underthe portions I9. The slides are held in position and againstdisplacement, preferably by means of strips 22 secured to the body ofthe frame and projecting over the edges of the slide, the stripsthemselves being held in position preferably by means of fastening bolts23.

J ournaled in the frame to extend thereacross is a shaft 24 providedwith cranks 25 disposed at an angle to each other, and connected to eachof the cranks is a pitman rod 26 secured thereto in any suitable manner,and mounted upon the free, end of each of these pitmans is a bearinghead 21, preferably of cylindrical formation. Each of these heads 2'! isseated in a block 28 which is disposed in a recess within the slide l8,and the head 21 has a recess 29 in th block 28 to rest upon a bearingsurface 30. The block 28 is held against displacement with respect tothe slide I8 by means of members 3| secured to the slide and extendingover the edges of the block.

The numeral 32 designates bearing members which contact with the edge ofthe block 28. on opposite sides of th recess 29. A screw 33 is threadedthrough the members 32 and tends to draw these members together or toseparate them, according to. the direction' of rotation of the screw 33.Whenthey are drawn. together, they contact the inclined faces 34 on theblock 28, to force the block againsta wedge-shaped member 35. Thismember 35 is inserted into the recess in the slide l8 occupied by theblock 28, andbetween the rear face of the block and the wall of therecess, and is provided with a flange 36, through which screws 31 pass.These screws are adapted to move the wedge-shaped member 35 in onedirection or the other, according to the direc tion in which the flange36 is operated. When one screw is operated, it draws the wedge-shapedmember in position so as to secure th block 28 to the slide 18. Shouldthe machine become jammed during operation, the wedge-shaped member 35is moved in the opposite direction, so as to loosen the block 28 withrespect to the slide l8, after which the wedge-shaped member 35 may bedrawn back into position.

' Carried by each of the slides I 3 and secured thereto in any suitablemanner, is a hammer head or upsetting tool 38.

Supported by the frame is a die 39 which may be removably held inposition in any suitable manner, and one of these dies is provided foreach of the slides l8 and its respective hammer head or tool 38. Thedies are provided with an opening 45 therethrough, in alinement with thehammer head or tool 38, and movable in the opening 40 is an ejector pin4|, preferably provided with a head 42. In the rear of each of theejector pins 4| is an anvil member 43 which is preferably provided witha rounded extremity 44 that abuts the head 42 of the ejector pin 4|.

A rocker member 45 is pivotally mounted intermediate its ends, as at 46,upon the frame |5 so as to move upon a vertical axis. One end 41 of thismember 45 is positioned toengage the end of the anvil member 43, and isalso positioned to engage an adjustable stop device 48. The other end ofthe member 45 is positioned to be engaged by a slide or bar 49 which issuitably supported, and which carries, at its opposite end, a roller 50that operates in a cam 5| secured to the shaft 24. When the shaft 24 isrotated, the slide 49 will .be reciprocated. During its movement in onedirection, it will engage the end of the member 45 and rock the sameforwardly about its pivot 45, causing the end 41 of the member 45 whichengages the end of the anvil member 43 to move forwardly, and therebyadvance' the ejector pin 4| to eject the work from the die 39. Whenejected, the finished work will fall through an opening 52 of themachine into a suitable receptacle.

When the slide 49 is moved backwardly by the operation of the roller 50in the cam groove 5|, the tendency of the slide or bar 49 is to moveawayfrom the member 45, but at that time, and as will be described, theanvil member 43 will be forced into engagement with the end 41 of themember 45, thereby moving the member 45 in the opposite direction aboutits pivot, until the end 41 strikes the adjustable stop 48, for apurpose to be described.

Mounted upon the frame of the machineare work-feeding rolls 53 (seeparticularly Fig. 5), one pair for each of the slides, and between whichco-operating rolls the work is fed, preferably in the form of a bar orrod. These work-feeding rolls are operated by means of intermeshinggears 54 individual to the pairs of feeding rolls, and which are carriedby the shafts 55 upon which the rolls 53 are mounted. Secured to one ofthe rolls of each pair, to rotate therewith, is a ratchet wheel 55 withwhich a pawl 58 mounted upon an oscillatable member 58 co-operates. Thismember 58 is pivotally mounted, preferably upon one of the shafts 55,and is oscillated about its pivot by means of a bar or rod '51 pivotallyconnected thereto, as at 59. The other end 50 of the bar or rod 51 isadjustablymounted in a guide-way 6| in a member 52, which latter ispivotally supported intermediate its ends, as at .63, upon a portion ofthe frame '|5. Carried by the other end of the member 62 is a roller 64which engages a suitable cam, preferably the cam 5| carried by the shaft24. When the shaft 24 is rotated, the cam 5| engaging the roller '64 onthe member 62, will rock the latter about its pivot 63, and therebyimpart a reciprocable movement to the bar or'rod 51.. This in turn willrock the member 58 about its pivot 55, and cause the pawl 58*, whichco-operates with the ratchet wheel 55, to move one step in the directionto feed the material between the feeding rolls 53,

By adjusting the end 66 of the bar or rod 51 in the guide-way 6| andsecuring it in its adjusted position in any suitable manner, the extentof rotation of the ratchet wheel 56 and, consequently, the feeding rolls53 may be varied to vary the amount of material fed to the machine. Thetension of the feeding rolls may be adjusted in any suitable manner,such as by means of a tension adjusting device 65.

Extending through the die 39 and in alinement with the bite of thefeeding rolls 53, is a tubular member 51 through which the stock orsupply of material is fed to the cut-off device and which tubular memberis also in proximity to the path of the reciprocatory movement of thehammer head or tool 38.

A cut-off device 68 is reciprocable across the end of the die 33 and theend of the tubular member 51, so that when the material is fed throughthe tubular member 81 by the feeding rolls 53, uponoperation of thecut-off device 68, a portion of the material will be severed from thestock. The extent of the feeding movement of the stock is controlled bythe feeding rolls 53 and the operating ratchet mechanism therefor. Theend of the stock will engage an adjustable stop 65 at the time when theslide I8 is in its rearmost position, as shown to the left in Fig. 9.

This cut-off device may be of any desired or suitable construction, andis mounted upon a slide Hi, and is operated by means of a member 7 1|which is pivotally mounted intermediate its ends, as at 12, upon asuitable member or bracket. A pin or projection 13 is carried by themember 1|, and projects between spaced collars 14 carried by the slide15.

The member 1| is operated by means of .a rod or bar 15, one end of whichis pivotally connected, as at 15, to the member 1|. and has connectedwith it, adjacent its free end, a roller 11 which operates in a grooveof a cam 18. When the cam 18 is rotated, the rod or bar 15 will bereciprocated, and this will impart an oscillatory movement to the member1|, to cause the cutoff slide 10 to be reciprocated.

In order to support the free end of the bar or rod 15, there may beprovided an enlargement 19 (see particularly Fig. 2) thereon, which isprovided with an opening in which is mounted a bearing block 3| that hasbearing upon theshaft 24. The bar or slide 49 (see particularly Fig. 2')is preferably provided with an enlarged portion 82 having an opening 33therein, so as to permit a connection between the cutter carrying slide15 and the member 1|.

In order to support the cut-off portion 84 of the stock and carry itfrom the position in which it was severed from the stock as it passedthrough the tubular member 61 (see particularly Figs. 9 to 12) and moveit into a position Where it will be in alinement with the hammer head ortool 33, to be forced thereby into the opening '40 in the die 39 andagainst the ejector pin 4|, any,

suitable means may be provided, such as a finger 85 which is yieldinglysupported, as at 86. This finger co-operates with the cutting area ofthe cutter 68, which latter preferably forms a recess 81 in the edge ofthe cut-off device, and the finger extends over the work 84 so that whenthe portion is severed from the stock, it will be held in this positionuntil such cut-off portion has been moved by the cut-off device 63 intoa position to be engaged by the hammer head or tool 38 and forcedthereby into the opening 40 in the die as.

A the cut-off device is advanced, the finger 85 will yield to pass overthe work, and then moves with the cutter to hold and carry the cut-ofipiece 84 forwardly. When the cut-oif piece is in this position, thehammer head or tool 38 will advance to move the stock 84 into theopening 46 in the die, and the cutter slide 10, with the cutter thereon,will be withdrawn. After a portion of the work 84 has been forced intothe die, the cutter device is drawn back and th finger 85 will yield anddisengage the work.. As the tool 38 forces the stock 84 into the die,the stock, when it en:-

gages the end of the ejector pin 4|, will force the latter backwardly,and also the anvil member 43, until it moves the member 45 about itspivotsufficiently to cause the end 4'! thereof to e gage the stop 48.This will occur at a time when a portion of the stock 34 projects infront of the die 39.

Upon further operation of the slide l8 and the tool or hammer head 38 inthe same direction; the projecting end of the stock will be upset, as at81 (see Fig. 9) to form a head on the end of the stock. This will occurfor the reason that when the end 4! is arrested in its movement underthe influence of the anvil 43, the anvil will become stationary,

while the slide l8 and hammer head or tool 38 advance forwardly to forma head. As the slide 58 recedes, th slide 49 will be advanced by theoperation of the cam 51 upon the roller 50, thereby swinging the member45 from the position shown at the right-hand side of 9 to the positionshown at the left-hand side of the same figure. Upon this movement ofthe member 45, the anvil 43 will be advanced, as will also the ejectorpin 4 l. to eject the work from the die 39 to a position that it willfall through the opening 52 in the frame.

The cranks 25 on the shaft 24 are arranged in opposition to each other,so that the slides l 8 and the hammer heads or tools carried therebywill be simultaneously operated in opposite directions. The feedingmechanism for the stock will also be alternately operated.

It will therefore be manifest that, with this improved construction ofmachine, there is provided a dual header, resulting in a continuouslyoperating machine, with the result that the speed of the operation ofthe machine will be increased and the cost of production decreased.

Further, this improved construction and operation is equally welladapted with equal efficiency for use in any kind of heading equipment,whether the equipment or machine is a solid die, or open die header, andalso whether the machine be of a single stroke, double stroke, or triplestroke operation.

While a single slide, with its opera-ting mechanism and associatedparts, has been herein specifically described, it is, of course,understood that the construction and operation of th other slide are thesame, and therefore such a specific description of one will applyequally to both of them.

While the preferred form of the invention has been herein shown anddescribed, it is to be understood that various changes may be made inthe details of construction and in the combination and arrangement ofthe several parts. within the scope of the claims, without departingfrom the spirit of this invention.
